Definitions

  • the present invention relates to a glass plate module that is mounted to a window frame of a structure.
  • Patent Literature 1 discloses a connection terminal that is connected to a defogger of a rear glass of an automobile. A configuration is adopted in which a connector for supplying a current from the outside is connected to this connection terminal, and the current supplied from the connector is supplied to the defogger via the connection terminal to cause the defogger to generate heat.
  • Patent Literature 1 JP H7-335280A
  • connection terminal such as described above is fixed to this conductive layer via an adhesive material such as solder.
  • this glass plate is conveyed to a structure such as an automobile to which the glass plate is to be mounted.
  • the connection terminal is conveyed in a state of protruding from the glass plate, and thus there is a risk that the connection terminal will catch on something during the conveyance route, and upon receiving an external force, the connection terminal will become detached from the adhesive material, or the adhesive material will crack.
  • the present invention was made in order to solve the foregoing problem, and it is an object thereof to provide a glass plate module that can prevent the connection terminal from becoming detached from the adhesive material and the adhesive material from being damaged, even in a case of receiving an external force.
  • a glass plate module includes a glass plate, a conductive layer laminated on the glass plate, at least one connection terminal fixed to the conductive layer, and made of a conductive material, and an adhesive material for fixing the connection terminal to the conductive layer, the connection terminal including a connector connection portion configured to be electrically connected to an external connector, one or more installation portions that are installed on the conductive layer, and electrically connect the connector connection portion and the conductive layer, at least one easily deformable portion that is provided between one of the installation portions and the connector connection portion, and is deformable due to an external force, and at least one protrusion provided anywhere between the connector connection portion and the easily deformable portion, and protruding in a direction in which the conductive layer extends and that intersects a direction in which the connector connection portion extends.
  • the connection terminal comes into contact with a worker or the like, for example, and receives an external force
  • the external force acts directly on the installation portion
  • the easily deformable portion that is deformable due to an external force is provided between the installation portion and the connector connection portion, and thus upon receiving an external force, the external force is received by the easily deformable portion, and is absorbed due to deformation of the easily deformable portion, and thus it is possible to prevent the external force from reaching the installation portion.
  • contact with an external obstacle is likely to occur at a position distanced from the installation portion by providing the protrusion anywhere between the connector connection portion and the easily deformable portion.
  • the protrusion protrudes in a direction in which the conductive layer extends and that intersects a direction in which the connector connection portion extends, and thus it is possible to prevent the installation portion from becoming detached and the adhesive member from being damaged, against the action of an external force from such a direction.
  • the connector connection portion includes an aspect in which a conductive wire is directly connected to the connector connection portion, for example, as well as an aspect in which a terminal with connector of a structure is connected to the connector connection portion.
  • the protrusion is provided between the installation portion and the connector connection portion, and this means that an aspect is also included in which the protrusion is also connected to the installation portion and the connector connection portion.
  • the protrusion protruding in “a direction in which the conductive layer extends and that intersects a direction in which the connector connection portion extends” at least means a direction that is not parallel with the connector connection portion and that intersects therewith, including being orthogonal thereto.
  • the direction in which the conductive layer extends does not strictly need to be parallel to the conductive layer, and it is merely meant to exclude an aspect in which the protrusion is orthogonal to the conductive layer.
  • the protrusion can protrude outward of a connection site between the easily deformable portion and the installation portion.
  • the protrusion can be coupled to the easily deformable portion.
  • the easily deformable portion can be configured such that both two end portions of a plate material elastically approach and separate from each other by bending the plate material.
  • connection terminal can be configured as follows. Specifically, a configuration can be adopted in which the connection terminal includes two installation portions and two easily deformable portions, one of the easily deformable portions is provided between one of the installation portions and the connector connection portion, and the other easily deformable portion is provided between the other installation portion and the connector connection portion.
  • the protrusion can protrude in a direction perpendicular to a direction in which the two installation portions are aligned.
  • At least one of the two easily deformable portions can be configured such that two end portions of a plate material elastically approach and separate from each other by bending the plate material.
  • At least one of the two easily deformable portions can be configured to be deformable by having a smaller width than the connector connection portion.
  • the adhesive material can be made of lead-free solder.
  • the installation portion can be formed in a circular shape or an elliptical shape.
  • the following effects can be acquired.
  • solder is used as the adhesive material
  • the solder becomes liquid when melted, and spreads in a circular shape. Therefore, if the shape of the solder when melted and spread and the shape of the installation portion are roughly the same, there is an advantage that stress is unlikely to concentrate when the solder shrinks at a cold temperature. Therefore, from the viewpoint that stress is unlikely to concentrate, there is also an effect that the impact resistance performance of the connection terminal is improved.
  • the glass plate module of the present invention even in a case of receiving an external force, it is possible to prevent the connection terminal from becoming detached from the adhesive material, and the adhesive material from being damaged.

  • Lead-free solder and leaded solder are known, and there is no limitation in particular as long as the solder can electrically connect an electroconductive connection terminal 3 such as described above and the defogger 2 .
  • lead-free solder whose Sn content is 90% or more will crack when joined to a laminated glass plate since the material is hard. Even in such a case, it suffices that soft lead-free solder such as indium solder and bismuth solder is used for the joining.
  • the above glass plate module 10 is conveyed along a predetermined conveyance route to an automobile in order to be mounted to a window frame of the automobile. At this time, there is a risk that the connection terminal 3 protruding from the glass plate 1 comes into contact with a worker, a working tool and the like.
  • the connection terminal 3 receives an external force due to the contact in this manner, if the external force acts directly on the installation portions 31 and 32 , there is a risk that the installation portions 31 and 32 will become detached from the solder 4 , or damage to the solder 4 such as cracks forming in the solder 4 occurs.
  • the shock absorption portion 34 that is deformable due to an external force is provided between the connector connection portion 37 and the installation portions 31 and 32 . Accordingly, when an external force is received, the external force is received by the shock absorption portion 34 , and is absorbed by the first section 341 and the second section 343 approaching and separating from each other, and thus it is possible to prevent the external force from being transmitted to the installation portions 31 and 32 . Furthermore, by providing the protrusion 35 at the end portion of the second section 343 of the shock absorption portion 34 , direct contact with the installation portions 31 and 32 is avoided, and contact with an external obstacle at a position distanced from the installation portions 31 and 32 is more likely to occur. In particular, the protrusion 35 protrudes in the right direction, and thus it is possible to prevent the installation portions 31 and 32 from becoming detached and the solder 4 from being cracked, against contact from this direction.
  • the protrusion 35 protrudes outward of the standing portion 33 , which is a connection site between the shock absorption portion 34 and the first installation portion 31 , and thus the protrusion 35 is more likely to come into contact with an external obstacle than the standing portion 33 . Therefore, it is possible to further prevent an external force from acting directly on the standing portion 33 , and the first installation portion 31 from becoming detached from the solder 4 . From this viewpoint, the end portion on the left side of the shock absorption portion 34 , namely the first curved portion 342 also protrudes on the right side relative to the standing portion 33 , and thus this portion also corresponds to the protrusion of the present invention.
  • the width in the right-left direction of the coupling portion 39 is made thinner than the connector connection portion 37 such that the coupling portion 39 is likely to bend. This makes it possible to absorb an external force, and to prevent the second installation portion from becoming detached from the solder 4 . From this viewpoint, the coupling portion 39 corresponds to the easily deformable portion of the present invention.

  • a shock absorption portion (an easily deformable portion) 54 in a U-shape in a plan view is coupled to the upper end portion of the standing portion 53 .
  • This shock absorption portion 54 is constituted by a trapezoidal first section 541 coupled to the upper end portion of the standing portion 53 , a curved portion 542 coupled to the end portion on the right side of this first section 541 , protruding on the right side, and curved rearward in a U shape, and a trapezoidal second section 543 coupled to the end portion on the left side of this curved portion 542 , and arranged in parallel to the first section 541 .
  • the first section 541 and the second section 543 are formed in trapezoidal shapes whose right end portions are cut away to be inclined, and the curved portion 542 is provided so as to couple these inclined portions.
  • the first section 541 and the second section 543 are formed substantially in the same shape, and are arranged with a gap therebetween, and the end portions on the left side of the first section 541 and the second section 543 are substantially at the same position.
  • a second curved portion 551 protruding on the left side and curved rearward in a U-shape is coupled to the end portion on the left side of the second section 543 of the shock absorption portion 54 , and a rectangular supporting portion 552 is coupled (to the second section 543 ) via this second curved portion 551 .
  • the supporting portion 552 extends so as to be parallel to the second section 543 of the shock absorption portion 54 and to be in contact with the second section 543 , and a connector connection portion 56 is coupled to the end portion on the right side of the supporting portion 552 .
  • the connector connection portion 56 is formed in a plate shape extending in the up-down direction, and extending backward.
  • This connector connection portion 56 is for inserting a connector (not illustrated) for supplying electric power or for grounding, and stoppers 561 protruding in the right and left directions are respectively formed on the two sides of the base end portion of the connector connection portion 56 , which is close to the supporting portion 552 . These stoppers 561 are for restricting the length of insertion of the connector.
  • a rectangular extension portion 57 extending in parallel to the standing portion 53 is formed at the lower end of the second section 543 of the shock absorption portion 54 .
  • the width in the right-left direction of this extension portion 57 is greater than the standing portion 53 . Therefore, the end portions on the right and left sides of the extension portion 57 protrude outward of the end portions on the right and left sides of the standing portion 53 .
  • a rectangular coupling portion 59 is then coupled to the lower end of the extension portion 57 via a third curved portion 58 extending rearward and curved downward so as to form a projection. This coupling portion 59 extends, due to the third curved portion 58 , rearward so as to be parallel to the first and second installation portions 51 and 52 .
  • the width in the right-left direction of the coupling portion 59 is the same as the extension portion 57 , and the length in the front-back direction of the coupling portion 59 is roughly the same as the connector connection portion 37 , and the position of the back end portion of the connector connection portion 56 and the position of the back end portion of the coupling portion 59 roughly coincide.
  • the second installation portion 52 is then coupled to the back end portion of the coupling portion 59 via a fourth curved portion 591 curved downward.
  • the size of the second installation portion 52 is the same as the size of the first installation portion 51 , and the second installation portion 52 and the first installation portion 51 are arranged on the same plane such that the positions in the up-down direction of the second installation portion 52 and the first installation portion 51 coincide.
  • this connection terminal 5 has the second curved portion 551 protruding on the left side relative to the shock absorption portion 54 and the extension portion 57 protruding on the right and left sides relative to the standing portion 53 below the shock absorption portion 54 , and these correspond to the protrusion of the present invention. Therefore, contact with the second curved portion 551 and the extension portion 57 protruding in the right and left sides relative to the standing portion 53 is more likely to occur, and it is possible to prevent direct contact occurring with the standing portion 53 and an external force from acting thereon. Accordingly, it is possible to prevent the installation portions 51 and 52 from becoming detached from the solder 4 , and the solder 4 from cracking, against not only contact from the right direction as in the first embodiment but also contact from the left direction.
  • the easily deformable portion according to the present invention is constituted by the shock absorption portion 34 or 54 and the coupling portion 39 or 59 , but there is no limitation on this, and it suffices for the easily deformable portion to be configured to be deformable so as to absorb an external force upon receiving the force.
  • the easily deformable portion can be formed of an elastic material such as rubber.
  • the shock absorption portions 34 and 54 are connected to the curved portion in the end portion on the right or left side of the first section, but for example, as shown in FIG. 12 , a shock absorption portion 6 arranged on the upper side of a standing portion 60 can be configured to have a curved portion 61 in the upper end portion thereof. Accordingly, the width in the right-left direction of a second section 63 can be easily made wider than the standing portion 60 .
  • the position at which the protrusion according to the present invention is provided is not particularly limited, and as in the above embodiments, the protrusion can be provided on the shock absorption portions 34 and 54 , but it suffices for the protrusion to be provided between the easily deformable portion and the connector connection portion, including on the easily deformable portion and the connector connection portion. Therefore, in the above embodiments, the protrusion may be provided on the connector connection portions 37 and 56 , the coupling portions 39 and 59 , and the like.
  • connection terminals 3 and 5 are each provided with two installation portions, but the number of installation portions may be three or more, or one. If one installation portion is provided on the connection terminal, the connection terminal can be constituted by the installation portion, the standing portion, the shock absorption portion and the connector connection portion, for example.
  • the protrusion of the present invention protrudes in the right-left direction, but may protrude in another direction.
  • the protrusion can intersect the connector connection portion in the right-left direction or the front-back direction rather than being parallel to the connector connection portion, and extend in a direction roughly parallel to a conductive layer such as a defogger (may also be inclined upward or downward with respect to the conductive layer).
  • connection terminal described in each of the above embodiments is an example, and the shapes, sizes and the like of the constituent members can be changed as appropriate.
  • shape of the installation portion may be other than elliptical, and may be circular, rectangular and polygonal.
  • the busbars 21 and 22 of the defogger 2 are divided, but may be formed integrally.
  • both the installation portions 31 and 32 of the connection terminal 3 , and both the installation portions 51 and 52 of the connection terminal 5 are arranged on the integrally formed busbars 21 and 22 .
  • any electrical component to which an electric current is supplied can applied as the conductive layer of the present invention.
  • an antenna may be applied.
  • the conductive layer and the installation portions 31 , 32 , 51 and 52 are connected using solder as the adhesive material of the present invention, but the adhesive material of the present invention does not have to be solder, and may be an electroconductive adhesive, for example.
  • connection terminal according to the first embodiment was manufactured as a working example.
  • the material of the connection terminal was copper, and the dimensions of the connection terminal are as show in FIG. 13 (the unit is mm).
  • a connection terminal shown in FIG. 14 was manufactured as a comparison example. Differences from the working example are as follows. First, as shown in FIG. 14 , a first installation portion 71 and a second installation portion 72 of the comparison example have configurations roughly similar to those of the working example, but do not have a standing portion unlike the working example.
  • a folded portion 73 having a mode similar to the shock absorption portion is provided above the first installation portion 71 , but a first section 731 and a second section 733 are in contact, and these are not configured so as to approach and separate from each other via a curved portion 732 . Also, a protrusion is not provided.
  • a first curved portion 74 and a connector connection portion 75 have configurations roughly similar to those of the working example.
  • a coupling portion 76 is wide, and has substantially the same width as both the installation portions 71 and 72 .
  • the dimensions are as shown in FIG. 14 (the unit is mm).
  • the installation portions of the working example and the comparison example configured as described above were fixed onto a conductive layer (whose material is Ag) laminated on a glass plate (air-quench tempered glass plate: the thickness 3.1 mm) using lead-free solder (Sn: 96.5% and Ag: 3.5%).
  • connection terminals of the working example and three connection terminals of the comparison example configured as described above were prepared, and an impact resistance test was performed on them.
  • an impact was given to the connection terminals of the working example and the comparison example fixed to the conductive layer by causing a weight of 30 g to hit from two directions from a height of 100 mm.
  • a impact 1 is a impact to the curved portion of the shock absorption portion of the working example, and is a impact to the curved portion of the folding portion of the comparison example.
  • a impact 2 is a impact to the protrusion of the working example, and is a impact to the right end portions of the first section and the second section of the comparison example.
  • the impacts 1 and 2 as described above were given 100 times at maximum. The results are as follows.
  • the impact 1 was given to all the three connection terminals 100 times, the connection terminals did not detach from the solder, and there was no damage to the solder.
  • the comparison example one of the three connection terminals detached from the solder at the 47th impact.
  • the impact was given to all the three connection terminals 100 times, the connection terminals dis not detach from the solder, and there was no damage to the solder.
  • the impact test could not be performed 100 times on any of the three connection terminals, and the connection terminals detached from the solder at the 9th, 37th, and 79th impacts, respectively.
  • the impact resistance performance was higher against a impact from the horizontal direction, in particular, a impact from the side on which the protrusion is provided. It is conceivable that this is because in the comparison example, the shock absorption portion and the protrusion as in the working example are not provided.
